Thanks for your reply !
Well I replaced the 2 prong igniter because of just that thought. I believe the sensor is in the igniter but I am no expect, just seems logical, I see no other sensor wires or devices.
Problem with all this is the 12vdc going to the gas valve coils are still on and active when the burner shuts off and stays on for about 5 seconds. So I don't think it an electrical thing ? but this is new to me, I'm an electronics tech and have worked on logic systems in the past.
The burner just stops for no apparent reason ? I there anything in the gas valve that might shut off if the propane pressure was to drop ? Like if the propane regualor is still not putting out enough ? I did replace it but the pressure on the secondary side can be held by my finger
